The invention relates to a gauge structure for measuring theV inside diameter, andthe parallelism of theedges of finished tapered or straight roller 4bearing cups.

.` In themanufacture of roller bearings,land

and operate as perfect-ly as possible when the inished vbearing is in use, -so that friction" will be reduced to a minimum.

i gauge which will simultaneously perfor-m the an improved gauge structure for gauging the parallelism of the opposite ends of the cup or cone :tor a roller bearing; to gauge theinside diameter of'such elements; toprovide a above two mentioned ,operations so as Yto simplify the gauging operation; and, lastlygen gauge structure for the purposes specied.

Briefly, these desirable objects are achieved in a gauge structure which, in the illustrative embodiment herein disclosed, includes a base and an upright frame, the base carrying in a particular manner to be described a rota-V table work holder, which includes means for permitting turning of the holder by hand. The upright frame carries in a particular manner a gauge which can be adjusted relative to the work and which also is so mounted that it may be moved to work engaging position or to a position tilted back away from the work, there being stops in lboth of these positions to hold the gauge in its place.

In the sheet of drawing accompanying this applicatiomc Y Figure 1 is a general side elevational view with the work on the holder shown ink seetion;

Figure 2 is a top plan view; Figure 3 is an end view of the gauge mounting with the gauge tilted back away from the work;

Vmounting the workholder and for turning it.

The gauge structureof this invention ernbodles a base 10, an upright frame 11, the

- bfase being hollowedout on its under side, as

indicated at 12, said base being Y provided with a vertical opening 13 adapted to receive the mounting element shown in Figure. 5,

which comprises a lower V.stud part 14 fitted into the opening 13, the lower end of the stud 14 having a reduced, vthread-ed eXtension 15 designed kto receive a conventional ring washer 16 and a nut 18'tor turnably securingV the structure of VFigure 5 to the base.

i This mounting part includes an annular The objects of the invention are to provide Y flange 19 provided with a series of linger hold pockets 20 along its peripheral edge,'and

above this hand operating annulus is a rest vided with a hole 23.

It will be understood that the sleeve 14 of.

the mounting 'member shown in Figure 5 is *dropped down through the hole 13 and Vturnerally to .provide an improvedfand simple ably heldin place bythe ring 16 and the nut and the annulus19 aspacer block 24 and a loose thrust ring'25 for the annulus to bear on. c

rPhe Work holder is shown in Figure 4:, and it comprises a flange 26 which rests on the restV 21, the `flange 26 having formed'therewith and thereabove a tapered plug part 27 18, there being mounted'between the base 10 Y 'IISV said plug at its top having an opening 28 of l shallow depth, which merges into a bore 29 adapted to fit over the stud 22 of the mounting part'heretOOre described. A lock plate` 30 fits into vtheV opening 28 with a screw 31 V passing through said plateandinto the opening 23 vin the study 22, thereby locking the work holder to' the mounting yand operating '90 member shown inFigure 5. A cone representing a piece vof work is shownA at 32 and this isritted over theplug 27K`in a positionv v ready to be gaugedf by means otra gauge,

which will now be described. y

The .upper end 'of the frame upright 11 is provided with shaft 33j carrying a ,fast

thumb screw-34 at one end, and, :at its other end, anarm 35 whicharm moves with the shaft V33, as itis fast thereon. This armv 35 carries a set screw 36 and, slidable over this screw, is a slotted bracket 37 formed on the body of a gauge 38, which in this illustration may be an indicator gauge having an indicator needle 39 and a needle operating means in the formof a plunger lOfcontactable with the work, vas shown in Figure 1, to operate therneedle 39 to give an indication. The screw 36V and slotted bracket 37 enable the 1.3 gauge to be given an adjusted set position with respect to the arm and relativeto the work on the work holder plug 27,4 as will be understood.

At two spaced points the upper'end of the upright 1l carries stop pins 41 and 42. Then the work is in position to be gauged as shown in Figure l, the arm 35 rests against the pin 4:2 to hold the gauge'in that positionand whenplacingwork on the work holder,` to provide clear entry for the work, Vthe operator turns the knob'34-to rock the shaft 33 to tilt the arm 35 and withit the gauge, upwardly and back to'the position shown in c j Figure 3, wherethe stop 41 functions to hold mthe gauge in its tilted back, raised position. In use, the gauge structure is assembled as has been indicated and the operatorplaces apiece of work V32, suchv for example as the so? conical or tapered vcup of a tapered roller bearing, onto the work holding plug 27. Then the gauge plungerI is made to engage the upper edge of the cone. The operator then by hand turns the flange 19 and this, of Sacourse, rotates the plug, as the part 14: is

Yloose in the opening 13 in the base. YAs ther work rotates, any inaccuracy in its dimensions as to height will be communicated to the plunger 40 to make the needle y39 indicate such 4,;1rregular1tv. Thus. the upper and lower edges can be gauged forv parallelism. Of

course, it will be understood that the plug 27/ f is.V a master plug and is perfect and thus, if the inner taper of the work 32 does not propgerly fit the cone plug, then the operatoralso knows that the inner` taper or inner diameter of the work is also inaccurate and, of course, such inaccuracy would also be communicated to the gauge indicator.

c From 'this disclosure it can now be appreciated that a gauge structure has been provided whichmeets all of the desirable objects heretofore described. l Y l It is the intention to cover all such changes andmodilications of the form herein shown j which do not materially depart from the spirit and scope of the invention as is indicated in the appended claims. j

What is claimed as new is:

`lng and a standard, an integral fixture comprising a horizontal rest with a vertical stud extending thereabove and another vertical stud extending therebelow, the lower stud fit- '"ting loosely in the base opening'turnably to l. In a gauge, a base formed with an openmount the fixture on the base, a masterpiece resting on the rest, means securing said masterpiece to the upper stud, said masterpiece being adapted to carry a complementary piece of work to be gauged, an arm pivotally connected to the standard, and a gaugehaving a work engaging element'carried by said arm.

2. In a gauge, a base formed with an opening and a standard, an integral fixture comprising a horizontal rest with a vertical stud extending thereabove 'and another vertical stud extending therebelow, the lower stud itting" loosely in the base opening turnably to mountv the fixturefon the base, a masterpiece resting on the rest, means securing said masterpiece tottheupper stud, said masterpiece being adapted to carry a complementary piece of work-to be gauged, an arm pivotally connected to the standard, a gauge having arwork engaging element carried vby said arm and adjustable thereon toward or away from the pivot of the arm, and means for securing the gauge in any selected position on the arm. l
